Water. It's the most common cosmetic ingredient of all. You'll usually see it at the top of ingredient lists, meaning that it makes up the largest part of the product.

So why is it so popular? Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation.

You'll also recognize water as that liquid we all need to stay alive. Talk about multi-purpose! If you see this, drink a glass of water. Stay hydrated!

What it does: Smoothing
Community Rating: Loved

Niacinamide has emerged as an all-star ingredient due to its many benefits.

It is known to treat acne by reducing inflammation. It also helps fade dark-spots and strengthen the skin by promoting the growth of the ceramide barrier.

Other benefits include smoothing wrinkles and minimizing redness.

The cherry on top? Niacinamide can also help build keratin, a protein that keeps skin firm.

When incorporating niacinamide into your routine, look out for concentration amounts. Typically, 5% niacinamide provides benefits such as fading dark spots. However, if you have sensitive skin, it is better to begin with a smaller concentration.

Niacinamide can be mixed with other ingredients to boost benefits. For instance, it has shown to be effective when used with copper, folic acid, and zinc to treat acne.

Tromethamine is an aliphatic compound. An aliphatic compound is an organic compound with open-chained carbon atoms. It is synthetically created. Tromethamine is used to balance pH and improve texture.

As an emulsifier, Tromethamine prevents oil and water ingredients from separating. This helps stabilize the product and elongate a product's shelf life. Tromethamine also makes a product thicker.

Tromethamine helps balance the pH level of a product. Normal pH level of skin is slightly acidic (~4.75-5.5). The acidity of our skin is maintained by our glands and skin biome. Being slightly acidic allows our skin to create an "acid mantle". This acid mantle is a thin barrier that protects our skin from bacteria and contaminants.

Oral Tromethanmine is an anti-inflammatory drug but plays the role of masking, adding fragrance, and/or balancing pH in skincare.

Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:

  • It is a solvent, meaning that it helps to dissolve other ingredients. This also enhances the absorption of the product into one's skin.
  • It is a humectant, which means that it helps attract moisture into the skin.
  • It helps improve product application.

Overall, Butylene Glycol is a safe and well-rounded ingredient. It is unlikely to irritate skin, and works well with pretty much all other ingredients.

Did not deliver
I have eczema-contact, atopic, and seborrhaic dermatitis. I also have melasma around my lips, on my cheeks, forehead, and around my eyebrows. I also have hormonal and fungal acne outbreaks periodically. I am also over 30 and starting to exhibit some signs of aging, specifically fine lines, bags, and discoloration on my forehead and around my eyes and mouth. I have used a number of different vitamin C serums including Tru skin’s and Klairs Juicy drop and have done a lot of research trying to find one that was gentle enough for my hypersensitive, eczema riddled skin but also effective. Unfortunately, although this serum had many positive reviews, I saw very little improvement with my melasma, fine lines or occasional flare ups of acne after using an entire bottle, twice per day-once in the morning and once at night. It smells nice, and it leaves a sticky sheen, which could be construed as a glow, upon application. I really wanted to love this product so I am quite disappointed with its performance and will not be repurchasing.
